What would happen if a mutation created a new allele that decreased fitness?

Answers

Answer 1
Answer: Fitness describes a reproductive success of an individual. For example, there are green and yellow beetles in a population. If a color affects the reproductive success, for example, green beetles will have more offspring that the brown ones because of their color. So, green beetles have higher fitness. And the beetles with decreased fitness will have less offspring.

So, if a mutation creates a new allele which decreases the fitness, the altered allele will not be inherited in such a ratio as the unaltered allele will.

A group of similar cells that perform a specific function is a(n)a. organ system.
b. organ.
c. tissue.
d. organism.

Answers

The answer is tissue. Hope this helps :D 

Final answer:

A group of similar cells that work together to perform a specific function in an organism is referred to as a tissue.

Explanation:

A group of similar cells that perform a specific function is known as a tissue. In biology, this refers to a level of organization in multicellular organisms. Collectively, these similar cells perform functions that benefit the entire organism. Examples include muscle tissue, which is responsible for movement, and epithelial tissue, which protects the body.

which of the body systems does not rely on the autonomic nervous system to stimulate involuntary events

Answers

Hey CarlenaRabern190,

The body systems that rely on the Autonomic Nervous System are the Digestive, Circulatory and Respiratory systems. Therefore the body system that does not rely on the Autonomic Nervous System would be the Skeletal System

Hope this helps!

The somatic nervous system does not rely on the autonomic nervous system for involuntary events.

The body system that does not rely on the autonomic nervous system to stimulate involuntary events is the somatic nervous system.

The somatic nervous system controls voluntary actions such as movement of skeletal muscles, while the autonomic nervous system controls involuntary actions such as heartbeat and digestion.

Two examples of systems that are controlled by the autonomic nervous system are the cardiovascular system, which regulates heart rate and blood pressure, and the respiratory system, which controls breathing rate and depth.

Answers

Answer:

This question is incomplete

Explanation:

This question is incomplete because of the absence of options but the complete question is in the attached picture below.

The human genome is the basic genetic code, or blueprint, for the transfer of traits from parents to offspring through -hereditary transmission- . Studying this code -has revealed- ways to partially correct genetic defects after birth. It is already clear that behavior is rarely controlled by -a single gene- . Rather, almost all behavior involves -multiple genes- , and often specific -environmental- factors influence how genes are expressed.

It would be noted that some of the options were not chosen at all, this is because this question focuses on genes and it's expression. "Nurture and education" and "psychological" are not factors that actually affect gene expression. Also, studying genetic codes has already revealed partial ways to correct genetic defects and hence it would be wrong to choose "may in time reveal". For instance, there are procedures used to identify genetic defects in the spermatozoa of a male which can be screened out and the "good" sperm used to fertilize an egg in-vitro.
